Legal claims defining the scope of protection, as filed with the USPTO.

1

1. An array substrate being mounted in a corresponding liquid crystal display panel, comprising: a plurality of scanning lines for transmitting scanning signals; a plurality of data lines for transmitting data signals; a plurality of thin-film transistors for transmitting the data signals to a plurality of pixel electrodes, respectively, according to the scanning signals so as to display images represented by the data signals; a first insulating layer disposed between the thin-film transistors and the scanning lines; and a second insulating layer disposed between the pixel electrodes and the thin-film transistors; wherein the first insulating layer has a thickness at two sides thereof relatively greater than that at a middle thereof, wherein the first insulating layer has a substantially quadrilateral outline in cross section; and the quadrilateral outline has a curved side which is concave-shaped.

2

2. The array substrate as claimed in claim 1 , wherein each one of the thin-film transistors includes a source electrode, a drain electrode and a gate electrode; a channel is formed between the source electrode and the drain electrode; the source electrode is connected to a corresponding data line; the gate electrode is connected to a corresponding scan line; and the drain electrode is connected to a corresponding pixel electrode.

3

3. The array substrate as claimed in claim 2 , wherein the source electrode is connected to the channel through an ohmic contact layer.

4

4. The array substrate as claimed in claim 2 , wherein the drain electrode is connected to the channel through an ohmic contact layer.

5

5. A liquid crystal display apparatus comprising a liquid crystal panel having a color filter substrate and an array substrate, wherein the array substrate has: a plurality of scanning lines for transmitting scanning signals; a plurality of data lines for transmitting data signals; a plurality of thin-film transistors for transmitting the data signals to a plurality of pixel electrodes, respectively, according to the scanning signals so as to display images represented by the data signals; a first insulating layer disposed between the thin-film transistors and the scanning lines; and a second insulating layer disposed between the pixel electrodes and the thin-film transistors; wherein the first insulating layer has a thickness at two sides thereof relatively greater than that at a middle thereof, wherein the first insulating layer has a substantially quadrilateral outline in cross section; and the quadrilateral outline has a curved side which is concave-shaped.

6
